This implementation dynamically adds the TokenKind variants, which means it also suffers from the same problems as the previoius "manual" implementation of enums: if you write e.g. `TokenKind.PUNCTUATION` in a program and typecheck it, it will throw an error since it doesn't recognize `PUNCTUATION` as a member of `TokenKind`.
I'm not sure why this one enum is outsourced to a different file and implemented via this dynamic registering approach. I'd be in favor of removing that and handling it just like the other enums.
